Kuulotaso

Kuulotaso refers to the lowest sound intensity that a person can hear at a specific frequency. It is a fundamental measure in audiology and is used to assess an individual's hearing ability. Kuulotaso is typically measured in decibels (dB) and is often represented graphically in an audiogram.

The measurement of kuulotaso is crucial for diagnosing hearing loss. Different frequencies, ranging from low bass sounds to high-pitched tones, are tested. For each frequency, the softest sound that a person can detect is recorded. This threshold varies from person to person and also depends on age and exposure to loud noises. A lower decibel value for kuulotaso indicates better hearing sensitivity.

Audiograms plot kuulotaso on a graph with frequency on the horizontal axis and intensity (in dB HL - Hearing Level) on the vertical axis. Normal hearing is generally considered to be within a specific range of dB HL across all frequencies. Deviations from this range can indicate different types and degrees of hearing impairment. Understanding kuulotaso helps audiologists and healthcare professionals determine appropriate interventions, such as hearing aids or other assistive listening devices. It is a key indicator of an individual's auditory health.
